Furthermore PCR type AN are very robust and environmental friendly as being air insulated and air cooled.

Easy connection and disconnection by Multi-Contact

Open design for air cooling, easy handling by swivel castors

Benefits

Due to the low-loss design and high Q-values of the PCR (well above 100 for power frequencies), the existing feeder provides a significant load range extension

Most economic solution for capacity extension

Robust design electrically, thermally and mechanically

Due to modularity very flexible adaption to the specific testing situation

Environmental friendly due to air insulation

Mobile or fix installations

Technology

The key to expand the load capacity as much as possible without modification of the existing feeder system is, to use reactors of low loss design. Conventional reactors do have an iron core. The iron core generates additional losses in addition to the copper losses of the wire. This drawback is overcome by MHVs ironless design. The reactors consist of “air” windings (even though oil insulated). These windings provide excellent electrical performance in steady state operation, as well as in transient conditions (flash over or breakdown of test objects). Furthermore, they have substantial better cooling performance compared to conventional reactor windings, enabling currents up to 5A per reactor without any thermal restriction and subsequent accelerated aging, due to thermal heating of the insulation.
